When these rays, after passing through anode, strike the zinc sulphide coating, a bright spot on the coating is developed (same thing happens in a television set). The flow of current from cathode to anode was further checked by making a hole in the anode and coating the tube behind anode with phosphorescent material zinc sulphide. These were called cathode rays or cathode ray particles. When sufficiently high voltage is applied across the electrodes, current starts flowing as a stream of particles moving in the tube from the negative electrode (cathode) to the positive electrode (anode). The pressure of different gases could be adjusted by evacuation. The electrical discharge through the gases could be observed only at very low pressures and at very high voltages. A cathode ray tube is made of glass containing two thin pieces of metal, called electrodes, sealed in it. In mid 1850s many scientists mainly Faraday began to study electrical discharge in partially evacuated tubes, known as cathode ray discharge tubes. However, the real credit for the discovery of electrons goes to J.J. G.J Stoney suggested the name of electron for the atoms of electricity. He stated that electricity is made up of particles called atoms of electricity. Michael Faraday showed that chemical changes occur when electricity is passed though an electrolyte.
